    Error when the system tries to suspend

    Lubuntu 16.04 64-bit

    When the system tries to suspend after I've been away from the computer, I've recently started to get this error from Power Manager.

    Code:
    GDBus.Error:org.freedesktop.PolicyKit1.Error.Failed Action org.freedesktop.login1.suspend is not registered
    When I go into the XFCE Power Manager, the options for System sleep more have been greyed out.

    I have no idea how to fix this problem. Can you help, please?

    EDIT: I see that I also no longer have the option to manually sleep.

    Does sudo pm-suspend work?

    Yes, it does, perfectly.

    I figured out the problem.

    Lubuntu has a recurring error where suspend does not work. Usually the fix is to make a small edit to the file /usr/share/polkit-1/actions/org.freedesktop.login1.policy. I had mis-edited it, and the error was so small that I missed it.
